hello 

I have another question that I can’t find the answer to by looking in the "configuration" or "Core settings" menus . It’s:
how to impose on startup the following presentation : a list of files window and, on its side, the corresponding tree structure?
Currently, I do 
each boot in the "menu" bar:  [ view --> split size --> 0/100  ]
Thank you in advance for your answers  !
cordially
SosPel
